Automation network range with spaces fails validation

[netniV]

Describe the bug
If a network range provided to automation contains spaces at the beginning or end, then it is incorrectly reported as failing when it should be trimmed.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Automation'
2. Click on 'Networks'
3. Edit a network
4. Set the range to something such as " 10.1.1.1" or "10.11.12.0/24, 172.172.0.*"
5. See the error

Expected behavior
In the above example, " 10.1.1.1" should become "10.1.1.1" and "10.11.12.0/24, 172.172.0.*" should be treated as "10.11.12.0/24,172.172.0.*". The code actually splits the ranges by commas, so it would be the individual entry that is trimmed.
