[BH-2065] Fix race condition between CMake targets

* Fix for the issue that resulted in race

engine to parallelize them. As a result,
databases were copied before their creation
has been finished, what resulted in weird
discrepancies in databases content and
occasional rsync errors.

* Removed unused multicomp_install
function.

* Refactored DB tests readContent
helper.
