7373 – (Regression git) Renamed imports conflict with other implicitly imported symbols

This is how to reproduce the regression:
 echo 'module m1; struct S {}' > m1.d
 echo 'module m2; struct S {}' > m2.d
 echo 'module m3; import m1; import S = m2; S.S s;' > m3.d
 dmd -c m3.d
This works without the fix, but with the fix I get this errors:
 m3.d(1): Error: m1.S at m1.d(1) conflicts with m2 at m3.d(1)
 m3.d(1): Error: no property 'S' for type 'S'
 m3.d(1): Error: S.S is used as a type
 m3.d(1): Error: variable m3.s voids have no value
The only important is the first one. If you change m3 like this it works again:
 echo 'module m3; import m1; import X = m2; alias X S; S.S s;' > m3.d

Thanks for the fix.
Maybe it would be a good idea to add the test case to the test suite to make sure this will never break again.
