Closes #685

Fix #618 ClasspathCrawler match file name only

Closes #618

See merge request orekit/orekit!190

These methods are incorrect. They should use the default implementation
instead.

Previously a null reset state behaved as CONTINUE with analytic
propagators but not with integrated propagators. This was an
undocumented "feature". Removed it to be consistent.

Previously ClasspathCrawler matched the whole path against supported
names which caused problems with ^ as other loaders only matched the
file name. Added a test case.

Fixed missing call to setMuCreated() in OemParser.
