Cannot change password when maxPasswordHistory is 1

[akiowata]

Issue Description

When I set passwordPolicy of maxPasswordHistory: 1,
reset password doesn't work at last step (after inputting a new password).

I found the process below has infinite loop.

parse-server/src/RestWrite.js

Line 1018 in a61ef7e

while (oldPasswords.length > this.config.passwordPolicy.maxPasswordHistory - 2) {

Steps to reproduce

1. Set passwordPolicy of maxPasswordHistory as 1.
2. Try resetting password.

Expected Results

That it works.

Actual Outcome

No responce.

@akiowata can you provide a workaround? and a PR? That should be an accessible one for a new contributor.

Exists a test for this scenario:

@paulovitin Is the test enough? It is already passing, right?
