Fix #1050 by filtering out invisible AppTy arguments
This makes the `synifyType` case for `AppTy` more intelligent by taking into consideration the visibilities of each `AppTy` argument and filtering out any invisible arguments, as they aren't intended to be displayed in the source code. (See #1050 for an example of what can happen if you fail to filter these out.) Along the way, I noticed that a special `synifyType` case for `AppTy t1 (CoercionTy {})` could be consolidated with the case below it, so I took the opportunity to tidy this up.
