tests ignores selected run configuration

Selected run configuration is not used when I run application from 'Test Results' panel. I wasn't able to find any other way to choose run configuration for tests. Please extend documentation if it is there.

Steps to reproduce:
1) select the run configuration
2) run test from 'Test Results'

Expected behaviour:
'./untitled6-tests -xml' is started

Current behaviour:
'./untitled -xml' is started

Workaround:
rename untitled6-tests target to auntitled6-tests to move it to the top of the list.

The test application untitled6 is attached as untitled6.tar.gz
