  BUG/TST: Fix for #6723 including test: force fill_value.ndim==0

Fix issue #6723.  Given an exotic masked structured array, where one of
the fields has a multidimensional dtype, make sure that, when accessing
this field, the fill_value still makes sense.  As it stands prior to this
commit, the fill_value will end up being multidimensional, possibly with
a shape incompatible with the mother array, which leads to broadcasting
errors in methods such as .filled().  This commit uses the first element
of this multidimensional fill value as the new fill value.  When more
than one unique value existed in fill_value, a warning is issued.

Also add a test to verify that fill_value.ndim remains 0 after indexing.
