Problem

nesting folders in a test/tags causes a panic that language not found for a path

Steps to reproduce

1. clone kylegoetz/tree-sitter-unison
2. create a test/tags/foo
3. run tree-sitter test
4. observe panic
5. rename directory foo to foo.u
6. run tree-sitter test
7. observe no panic

So something about the tag tests expect paths to have names that end in the file extension of an available language

Expected behavior

I expect paths to not have to have a mock file extension matching an available grammar language

Tree-sitter version (tree-sitter --version)
