Fix problem formatting percent symbols.
Fix crash due to access of unretained value.

For some reason the crash only occurs in some environments.
Fix wrong descriptions in the unordered collection matcher.

Matching the collection always worked on the same mutable array instance of
matchers. The second round of matching (for the description) therefore
reported the wrong mismatch.

The tests did not reveal this problem, because the assert method exercised
the matching only once.
Change forward declaration to import for convenience.
