Move log prints from test-ctor to test-inst-ctor

Move log prints from test-ctor to test-inst-ctor

Some of the tesselation tests were printing values into the output log
from the test constructor, which meant that said prints end up in more
or less random place in the log. Moved those prints to the test instance
instead, so the information now resides within the test output.

The prints were also done in the amber-verify run mode.

Affects:
dEQP-VK.tessellation.geometry_interaction.scatter.*
