Bump pom-scijava

Fiji will use our sample image uploader, for which it has to provide
a StatusService and a LogService, the latter based off of the new
scijava-common library's AbstractLogService.

Play nice and use the same pom-scijava version.

Provide a pure Java API for the SampleImageUploader

Fiji will learn how to have its own ImageJ2 context, but we need the
sample image uploader in a hurry...
