TileSet: Don't error out on tile_ getters with wrong shape id

Partial revert of 02319dceb2e17184eb765c67719a306f56dafc1b,
previous code handled this cases without errors and the TileSet and
TileSetEditorPlugin are written with the expectation that those will
not error out.

This is a bit wonky and these classes should likely be refactored,
but until then it's best to keep things as they were.

Fixes #29962.
