Asset entry breaks upon creating multiple assets, if the same serial is used twice.

Describe the bug

When creating multiple assets at once: if you copy-paste a serial that's been already used in that queue, Snipe IT does not warn you about this and instead, creates only one instance of the asset and skips one asset number. This also causes the auto-increment to break and keep offering the latest asset tag, which has already been used. This can be fixed by either changing the auto-increment to +1 of the offered one or by going through the latest asset tags and manually tracking down which value was skipped and then using it.

Reproduction steps

1. Create new asset
2. Add another asset to create from the "+"-icon
3. Enter a serial to the first asset
4. Copy-paste the serial to the second asset
5. Fill out rest for the forms as you please
6. Press save

Expected behavior

An error message should appear about reusing the serial number.
