Check_MK Werk 4702: Quicksearch: fixed minor parsing issue when using specific filters

ID: 4702 Title: Quicksearch: fixed minor parsing issue when using specific filters Component: Multisite Level: 1 Class: Bug fix Version: 1.5.0i1 The first character of the entered search text was not evaluated correctly, whenever specific filters, e.g. <tt>s: Check_MK</tt> where used. This didn't cause much trouble, since the search itself was an infix search.
