Fix tag search to not require wildcards

[Tyrannicodin]

Previously, searching for tags required % wildcards to be added either side in order to search for a tag without an exact match, however this removes that requirement.

please add a test for this scenario, so there wont be any regression in future, thanks.

Sorry, I'm not sure how test for this, since it was purely an issue with the SQL interaction and I can't see any other examples of a SQL test.

here's a test for tag name lookup, so you can add it there:

TagStudio/tagstudio/tests/test_library.py

Lines 77 to 90 in af642a7

	def test_tag_search(library):
	tag = library.tags[0]
	assert library.search_tags(
	FilterState(tag=tag.name.lower()),
	)
	assert library.search_tags(
	FilterState(tag=tag.name.upper()),
	)
	assert not library.search_tags(
	FilterState(tag=tag.name * 2),
	)

Looking on the test again, it would be better to use @pytest.mark.parametrize() similarly as here, but that's optional:

TagStudio/tagstudio/tests/test_library.py

Lines 342 to 350 in af642a7

	@pytest.mark.parametrize(
	["query_name", "has_result"],
	[
	("foo", 1), # filename substring
	("bar", 1), # filename substring
	("one", 0), # path, should not match
	],
	)
	def test_search_file_name(library, query_name, has_result):

Added a test 👍
