Auth works when resolving a target platform over a composite mirror.

RemoteMetadataRepositoryManager now passes the effective URI to the
MavenAuthenticator instead of the original one. This fixes eclipse-tycho#3501.

This commit also includes the test that was used to reproduce the bug:

- testTargetDefinitionAuthMirror: tries to resolve a target definition
from a composite p2 repository accessed over an authenticated composite
mirror.

Also, several other tests have been created just for completion:

- testAuthMirror: tries to access a composite p2 repository over an
authenticated composite mirror.
- testMirror: tries to access a composite p2 repository over a composite
mirror with no authentication.
- testRepositoryEncrypted: tries to access an authenticated composite p2
repository whose password is encrypted.
- testTargetDefinition: tries to resolve a target platform from a
composite p2 repository.
- testTargetDefinitionEncrypted: tries to resolve a target definition
from an authenticated composite p2 repository whose password is
encrypted.
- testTargetDefinitionMirror: tries to resolve a target definition from
a composite p2 repository accessed over a composite mirror with no
authentication.
