Fixed bug #15917: unexpected complain for a NIST test case.

Browse Source 
The problem was due to the fact that with --lower-case-table-names set to 1 
the function find_field_in_group did not convert the prefix 'HU' in
HU.PROJ.CITY into lower case when looking for it in the group list. Yet the
names in the group list were extended by the database name in lower case.
