Add log intensity to available projections.

All high dimensional analyses should use the log intensity instead of
the raw intensity. See: https://jira.thehyve.nl/browse/UAT-136
Add protein retrieval test for log intensity.
Remove stale test code.
Improve ProteinEndToEndRTests for logIntensity
Remove debug statement.
Add RNA Seq test for log intensity.
Rename delta to DELTA and rbmData to data.

In order to be consistent with the other data retrieval tests.
Add RBM test for log intensity.
Add MiRNA test for log intensity.
Add MRNA test for log intensity.

Dubious adding of 'scale: 4' to the domain model. This brings it in line
with the other domain models but really was added because the DELTA
otherwise wasn't big enough.

Some 'LOG_INTENSITY' columns in the database have different types
anyway. Most are NUMBER, some are NUMBER(18,4).
Add metabolomics test for log intensity.
Adds log intensity projection to the tests.

Only to the tests which already test for this.
