This PR removes tests which have better alternatives in seq submodule since #387.

Also, while working on namespaces support, I accidently found a bug in a deserializer, so I've added a test and a fix for it.

This is a much more complex test than the one that replaces it (https://github.com/tafia/quick-xml/blob/d34b77972ccaad505c3348761382fe7d01ca49ce/tests/serde-de.rs#L1261=), is it really a full replacement?

Actually, yes. The mapping should be independent and composable, so we shouldn't bother of internals of the MyEnum type (or Item type in Project). For now we don't have a tests that ensures that mapping is really additive in all cases (which is why #435 is happened), but

  • that check should be added explicitly and for all combinations
  • in that test mapping is independent and composable

I'll plan to add necessary tests that would ensure that mapping is always composable (may be in form of doctests in #369)

I used the merge conflict cleanup feature just to try it out - you can squash that commit if you want.

The history becomes too confusing because of the back-and-forth merges. I'd rather do a rebase.
