Fix bug where removing projects with assets fails

rrmdir() function needed to specify its own location when calling itself
recursively (i.e., $this->rrmdir() instead of rrmdir()). This would only
happen if the project's assets directory contained other directories, so
it never triggered before.
fixup failing tests resulting from change of interface to get UI working. Refactor test setup into LexiconMongoTestEnvironment.
Merge remote-tracking branch 'lf/master' into feature/fileupload
re-factor tests to use Mock environment setup and cleanup.
