`core search` does not contain board name after `core update-index`.

Bug Report

Originally from here: arduino/arduino-pro-ide#21
core search does not contain 3rd party board names after code update-index.

Current behavior

The board names are missing.

Steps to reproduce:

Here are the steps to reproduce the problem with the CLI only. I am not sure if this is an IDE problem, maybe the way we update the index and run the search from the IDE is incorrect.

1. Wipe the previous state if any:

rm -rf ~/Library/Arduino15

2. Check the CLI version:

./arduino-cli version

3. Update index with a 3rd party core:

./arduino-cli core update-index --additional-urls https://tician.github.io/arbotix/package_trossen_arbotix_index.json

4. Run a wildcard seach for all cores:

./arduino-cli core search --additional-urls https://tician.github.io/arbotix/package_trossen_arbotix_index.json

5. Install the arbotix:avr 3rd party core:

./arduino-cli core install arbotix:avr --additional-urls https://tician.github.io/arbotix/package_trossen_arbotix_index.json

6. Update the index without the URL of the previously installed 3rd party core:

./arduino-cli core update-index

7. Run a new platform search with the additional core URL; you can see the 3rd part core and its Name:

./arduino-cli core search --additional-urls https://tician.github.io/arbotix/package_trossen_arbotix_index.json

8. Run another platform search without the additional core URL; you cannot see the Name of the installed 3rd party core:

./arduino-cli core search

All in one (you can see the final search does not contain the Name of the installed 3rd party core):

rm -rf ~/Library/Arduino15 \
&& ./arduino-cli version \
&& ./arduino-cli core update-index --additional-urls https://tician.github.io/arbotix/package_trossen_arbotix_index.json \
&& ./arduino-cli core search --additional-urls https://tician.github.io/arbotix/package_trossen_arbotix_index.json \
&& ./arduino-cli core install arbotix:avr --additional-urls https://tician.github.io/arbotix/package_trossen_arbotix_index.json \
&& ./arduino-cli core update-index \
&& ./arduino-cli core search --additional-urls https://tician.github.io/arbotix/package_trossen_arbotix_index.json \
&& ./arduino-cli core search

End of the output:

I can confirm, it results in an incomplete state in the Pro IDE:

Expected behavior

The board names are available.

Environment

• CLI version (output of arduino-cli version):
• OS and platform:
