Fixing failing unit tests

Initial fix for failing unit tests.

I had a look at the patch, it does a bit too much.

You added "../" on many include/require lines, which completely breaks the rest of pma.

For tests there are some calls to chdir() to the pma root dir. It might work for you because of a missing chdir statement.

Please try to solve this chdir()'ing to the correct dirctory.

Also changing example configuration looks like a bad idea to me. It should contain only bits, which user might be interested to change.

Thank you both for the comments :
just to ensure that I am starting with correct first steps I will mention the steps I followed after your comments.
- First I 'git checkout' ed all the files I did the ./ --> ../
- Instead of sample config used /pma-root/setup/frames/config.inc.php. Is this the correct one to edit? (If we can add this full path in the "Unit Testing" part of the wiki it will help new comers I think)

Your thoughts?

That would be a way to undo those changes.

No, these setting are not relevant for normal users.
I think they should be located alongside the tests. We could place a test/config.sample.inc.php in Git and let users copy this file to test/config.inc.php in their own checkout. Git can be instructed to ignore the copied file.
