ID in email notification has wrong format

[grisu48]

The ID in the email notification is formatted in exponent format, which is odd:

Message from https://publiccloud-ng.qa.suse.de/

Provider      id       Created-By   Namespace    Age                        Delete                       openQA
===============================================================================================================
GCE        5.556e+18   <redacted>     ccoe        12h1m   <redacted>

The id field is displayed as 5.556e+18, which indicates a ridiculously high ID number. Either the formatting is wrong or the id is weird.
