Increase column size for processdefinition id

Since the use of uuid's the ID_ field size (64) is too low for process definitions as the uuid almost takes all the space from the field. We hit the size limit of the field when we use a key that's a bit longer, when this happens the ID_ field does not include the key.
Normally the ID_ field should look like this KEY-uuid.
So when I request a process I can't see the definitionKey instantly, then I have to do an extra rest call just to know the definition key.

field: ID_
table: ACT_RE_PROCDEF
