generate: handle non-string values for IDs

Updates the name generation to handle scenarios where the ID is not a
string value. This is incredibly uncommon (logpush is the only service
exposing a non-string hash value) however this will fix the crash while
I chase up the internal team whether this is intentionally different.

Fixes #248
