Fix to use CVSRepository getRepoCommand() in test

[idodeclare]

Hello,

Please consider for integration this tiny patch to fix CVSRepositoryTest to use CVSRepository getRepoCommand(), so that the test uses a developer's environment override of cvs command.

Thank you.

weird, I thought repo init will init the SCM command from -d variables ...
(but perhaps cvs needs a fix in this regard)

I can merge this(didn't look at how we do it for other repos and whether the logic to isolate overrides from within repos works well for all SCM providers), so I hope my trust here is OK and you did verify the others ;)

I know that for e.g. git or hg this override works well (since I override them on windows dev env with -d to fit custom binaries on windows)

merging, let's see if I am wrong or not :)

Yes it was just this test that was running a non-overridden command. Thank you, Lubos!
