Code Modernization: Use correct default value for JavaScript translations path.

The $path parameter of load_script_textdomain() had a default value of null, but would be passed onto the untrailingslashit() function without any input validation, even though the latter explicitly only expects/supports a string input.

This commit changes the default value for $path to an empty string, and adds an is_string() check before passing the value to untrailingslashit() to fix the issue at the point where the invalid input is incorrectly (not) validated.

Note: Changing the untrailingslashit() function is outside the scope of this commit.

Includes:

  • Adding a dedicated unit test for this issue.
  • Correcting the default value for $path from null to an empty string in a few related methods and functions:
    • WP_Dependency::set_translations()
    • WP_Scripts::set_translations()
    • wp_set_script_translations()
    • load_script_textdomain()

This fix also allows to remove a couple of calls to expectDeprecation() in unrelated tests.

Fixes an error when running the test suite:

4) Tests_Dependencies_Scripts::test_wp_external_wp_i18n_print_order
rtrim(): Passing null to parameter #1 ($string) of type string is deprecated
