Update parent pom reference to version 4.1.0.Alpha2-SNAPSHOT

Update to the latest version. We had 4.1.0.Alpha1-SNAPSHOT which
recently stopped working because it points to now non-existent
TP 4.30.5.Alpha-SNAPSHOT. We should be using parent
4.1.0.Alpha2-SNAPSHOT until 4.1.0.Alpha2 is released and then
we'll move to that.
Modified MylynBugzillaQueryTest.java for Mylyn tests - replaced code
that attempted to access UI elements with differing names between
versions of JBT/JBDS, and then trapped exceptions for mismatches, with
code that actually determined the running JBT/JBDS product and version.
The new code is more reliable and able to better handle Red Deer
exception changes.
JBIDE-13770 Update integration-tests plugin versions to 4.1 in master

This is something that we should have done when master became JBT 4.1.x.
So let's at least do it now. Right now most test plugins are version
4.0.0-SNAPSHOT in both master and jbosstools-4.0.x branch.
I verified that everything can be built.
Increasing Code coverage on OpenShift Enterprise Job.
Updated Mylyn POC tests to stay insynch with Red Deer changes and to
remove commented out code. This restores the tests to the successful
working state that existed on March 14 - the next update to these tests
will be a complete redesign to match the Red Deer model for a separate
view object for Mylyn.
