Process Mining update license code

Issue description:Process mining: Missing License Field Format

Resolution:

1. If one have a new license code (i.e. actually a different code), then one needs to deactivate the current code first using the 'deactivate' option and then it will allow to enter your new code.

2. In another scenario, The thinking is that existing license would just be extended (given a new end-date), so pressing update would be all one would need to do.
