The thing is that all dependecies get split into <Name, nsType> tuples
(foo(bar) becomes <bar, RPMNS_TYPE_foo> and _rpmtsCheck was using
only the Name half from this tuple for all tests.

The real problem that I was afraid to touch to avoid messing things up
is lib/rpmal.c:rpmalAllSatisfiesDepend() which seems to work on global
lists instead of private copies which caused the infinite loop because
it decremented interator in rpmds 'provides' list for a transaction.

Didn't find any, but I was only looking at this particular problem.
