commit 62c3ad2b0d67c376b5d5d1ce894ad9942531769c

    Make empty string always return value from `idris-process-filter`
    
    Why:
    In commit: 74731b53caa6b2a2a was introduced regression by moving the ""
    inside of the if expression causing it being return value only in some
    cases.
    The return value from idris-process-filter is written into idris-process
    buffer and
    after commit 74731b5 this become mostly the output of idris-connect
    which consequently returns idris-words-of-encouragement.
    Because now the *idris-process* buffer is not empty it is moved to the
    front and interrupts users workflow.
    
    Downside of this fix is that the words of encouragement
    may be lost from users sight due to another messages when loading
    file to Idris. This will be addressed in separate commit.
