[BUGFIX] Exception when setting "language" to "all" for content elements

Currently you get an error in the backend when you try to set the
language to "all" for a new or existing content element (integer was
expected but null received triggers PHP strict type error).

The reason for this is, that the DataMapProcessor tries to sychronize
elements from tt_content with uid 0.

This patch adds an integration test that content elements without an
existing source do not get synronized.
