testing: make Mobical eds_events testItems test pass

Mobical seems to have switched its time handling. Several floating
time stamps are converted to UTC, using the time zone set on the
server.

This breaks all-day detection and EXDATEs. This used to work in the
past (http://bugzilla.moblin.org/web/bug_report_3009.html). Instead of
trying to find further workarounds, let's give up and declare these
aspects as unsupported: README updated, test data simplified.
