More robust Tags plugin MPD filter configuration

Remove external enclosing parentheses in user defined MPD filter, for
instance when there is more than one expression:
    ((genre == 'rock' ) AND (date =~ '198.')).

Even though it's a valid MPD filter, forge_filter will enclose it
properly. We do not want to through a syntax error at users since it's a
valid MPD filter, hence trying to transparently reformat the filter.

filter = ((genre == 'rock' ) AND (date =~ '198.'))

  and

filter = (genre == 'rock' ) AND (date =~ '198.')

Will work the same, producing the valid MPD filter:

    ((genre == 'Punk') AND (date =~ '198[2-9]+') AND (artist != ''))
