Don't search more generic icons in Applications and MimeTypes contexts

According to the specification
https://specifications.freedesktop.org/icon-naming-spec/icon-naming-spec-latest.html#guidelines
1) "the dash “-” character is used to separate levels of specificity in
   icon names, for all contexts other than MimeTypes"
2) "the “Applications” context should not use this method of falling
   back to more generic icons"
