/id-calc confuses UNIX timestamp fields #556

Describe the bug
The /id-calc command shows both the UNIX timestamp in seconds and the UNIX timestamps in milliseconds. However, these fields are switched i.e. the field with milliseconds clntains the value with seconds and vice-versa

Steps to reproduce
Run /id-calc with a Discord-ID, e.g. /id-calc 358291050957111296
Check the fields for the UNIX timestamp.

Expected behavior
The Unix-Timestamp field should contain the number of seconds since 1.1.1970 while the Unix-Timestamp (+ milliseconds) field should contain the number of milliseconds since that date.
