APIv3 - Fix overzealous pseudoconstant matching

[colemanw]

Overview

Fixes regression caused by #22282.

Before

An api3 call like this would fail due to strict case matching:

civicrm_api3('CustomGroup', 'get', [
  'extends' => "contact",
]);

After

Works fine. SQL is case-insensitive so there's no reason not to allow it.

Technical Details

Strings do not need to be strictly matched to pseudoconstants during get operations.

test fails relate IMO @colemanw

[colemanw]

Ok, I've fixed one test by throwing the expected API_Error in that particular function. The other two tests were IMO just plain bad. They were testing a quirk of the APIv3 Contact Query Object which they expected to fail in a particular way and now it doesn't. But I see no reason why it should have failed that way, and all other tests are passing. So I removed them.
