system-filter: Prevent text wrap, and keep field list dropdown for functions

[hanneskuettner]

Scope

Two minor improvements for the system-filter interface:

• Make sure that long plain names don't wrap:

Before	After

• Handle fields with function names the same as field names when it comes to dropdown behavior. Previously, fields with function names were not identified as existing fields and only displayed as plain-name and one had to manually remove the filter and re-add it with a different field if a function was selected. Now, it behaves just like a normal field name and shows the dropdown on click.

What's changed:

• Minor CSS change
• Extend isExistingField to account for function names in the last key part (which is AFAIK the only part that can have a function?)

Potential Risks / Drawbacks

None

Review Notes / Questions

• Does this warrant a changeset?
