Fix Test Reports for Skipped Tests

When a test was skipped because, say, Redis was not available
the tests showed as passed in the test report. They should
show as ignored.

Add a call to Assume.

Report now shows:

Test		Duration	Result
testDelete		-	ignored
testFindAll		-	ignored
testInitialState	-	ignored
testSave		-	ignored

Vs:

Test		Duration	Result
testDelete		0s	passed
testFindAll		0s	passed
testInitialState	0s	passed
testSave		0s	passed
XD-900 Phase II - PropertyAccessors to Common

PropertyAccessors are now inheritable in SI contexts.

Instead of adding them to every module, move to module-common.xml.
XD-792 Use SI twitter search support.

TwitterSearchMessage source was a temporary fix to provide
authenticated twitter search until it was supported by Spring
Integration.

However, we still need a customised versions of TwitterTemplate
which can be configured with the consumerKey and consumerSecret as
Spring Social doesn't provide a matching constructor which will obtain
an OAuth2 bearer token internally.
