Fix bogus mass-conversion equalsAsciiL -> startsWith

3af99e4d59d89c343965a928681a30f36b1007d2 "convert equalsAsciiL calls to
startsWith calls" should rather have converted to oprator ==.

(None of those bogus startsWith calls seem problematic enough to warrant
backporting also to libreoffice-4-2-0.)
