[LyX/master] Cmake export tests: Allow deeper label nesting.

    Cmake export tests: Allow deeper label nesting.
    
    Previously all labels got the depth '7' while processing 'suspiciousTestss'.
    The depth is used to sort how our labels are used to build a test-label.
    
    Say a test gets label a, b, and c, with depth 3, 8 and 2.
    The constructed test-label will be "b:a:c"
    For new (to be implemented) 'reason-labels' it is more convenient to assign 
them higher values.
