ci: enable more tests on Postgres adapter

[cbaker6]

New Pull Request Checklist

• I am not disclosing a vulnerability.
• I am creating this PR in reference to an issue.

Issue Description

A number of test cases are not enabled for the PostgresAdapter though the adapter is able to pass the tests. This can be for a number of reasons such as:

• functionality was implemented when tests was originally created, but adapter now has functionality
• by mistake or oversight

Most of the other tests that can't pass are either legacy tests from the original Parse Server, from legacy versions of the servers, or tests that use specific mongo functionality.

In addition, some tests are incorrectly labeled to be excluded from postgres, while they specifically should say they should only run on mongo.

Close #7640

Related issue: #7640

Approach

Enable 17+ tests that are able to pass. Modify certain tests designed for mongo to run on both adapters.

With the changes, Postgres runs 2672 of the tests compared to Mongo running 2808 tests, meaning Postgres runs >95% of the tests Mongo runs in the test suite. Another way to look at this is the total amount of tests is 2876. Postgres passes 93% of the test suite while Mongo passes 98%.

TODOs before merging

• Add test cases
• Squashed 2 bugs that caused CI to randomly fail in ParsePolygon due to not waiting for async call to finish before tests began:

parse-server/spec/ParsePolygon.spec.js

Line 213 in 80bf578

beforeEach(() => require('../lib/TestUtils').destroyAllDataPermanently());

parse-server/spec/ParsePolygon.spec.js

Line 428 in 80bf578

beforeEach(() => require('../lib/TestUtils').destroyAllDataPermanently());
