tests-mbed_hal-common_tickers: fix bug in ticker increment test case 

It is possible that the difference between base and next tick count on some platforms is greater than 1, in this case we need to repeat counting with the reduced number of cycles (for slower boards).
If number of cycles has been reduced than base tick count needs to be redefined. This operation is missing and is added by this patch.
