tdf#94173: Calc doesn't save your own created autoformat presets

Auformat list (maData) is defined as "MapType" which itself is defined like this:
boost::ptr_map<OUString, ScAutoFormatData>
so default sorting is ascii

2 consequences:
1) Default didn't appear first
2) When adding a new autoformat entry when it was new first one of the list
wasn't saved because of iterator was incremented first before looping
See https://bugs.documentfoundation.org/show_bug.cgi?id=94173#c5
There were some other weird behaviors too according to comments of the bugtracker

Regression from http://cgit.freedesktop.org/libreoffice/core/commit/?id=72c1b6141d590fb4479925ed8bc88b79357c2bfc

Solution:
Add a Compare so Default entry is always first one so the first time incremented iterator is ok and
new entry (even if new first one in list) is saved

Thank you Markus for the idea! (I was lost in Compare syntax)
