[FIX] account: handling of text domains in _query_get

1df72cb01b added a stringification of
the domain parameter to handle situations where an actual
domain (list/tuple) is being provided rather than a string, however
this causes issues when the string input is text (unicode) containing
non-ascii data as in Python 2 `str()` will then raise a
UnicodeEncodeError.

Rather than stringify the input, bypass safe_eval when the input is
already a proper domain.

Closes #19367
