Fix width on inject node property

[kazuhitoyokoi]

• Bugfix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)

Proposed changes

On the inject node property UI, the pull-down menu and checkboxes are wider than specified values. This problem seemed to occur because the order of the styles to apply was changed in Node-RED v1.0.0. Therefore, I added !important to set higher priority.

Checklist

• I have read the contribution guidelines
• For non-bugfix PRs, I have discussed this change on the mailing list/slack team.
• I have run grunt to verify the unit tests pass
• I have added suitable unit tests to cover the new/changed functionality
