Misc test fixes for doctrine/mongodb 1.1.x

Update Cursor/Builder/Query constructors and delete LoggableCursor

Updated the constructor signatures for Cursor, Builder, and Query classes. See: https://github.com/doctrine/mongodb/commit/39a2b7c7567b4609a58f3ea3f408d872fdbb7440#diff-10

ODM's LoggableCursor class only served to log sort() calls with unprepared field names. The wrapped LoggableCursor already logs its own sort() call (with prepared field names).
