hellofromTonya 243e75eb41 Code Modernization: Fix null to non-nullable deprecation in term_exists(). 
The `term_exists()` function expects a string or an integer for the `$term` parameter. It validates for integer, but not for string or `null`.

One of the pre-existing test cases, passed `null` to the function, leading to a `trim(): Passing null to parameter #1 ($string) of type string is deprecated` notice on PHP 8.1.

Fixed now by doing a cursory check on the variable at the start of the function and bowing out early in case the `$term` is `null`.

The issue was discovered via and is already covered by the `Tests_TermExists::test_term_exists_unknown()` test method.

Follow-up to [15220]. [38716].

Props jrf, hellofromTonya.
See #53635.
