fix importing campaign/event ID on a contribution starting with a number

[MegaphoneJon]

Overview

If you have a campaign or event whose title starts with a number e.g. "26FY donations", and you import a contribution using that title, it will be treated as a campaign ID (in this case, 26) if that campaign ID is found first.

It appears that events have the same issue.

You can replicate this by creating a new campaign starting with 1, e.g. "1 test". Import a contribution with the Campaign column set to 1 test.

Before

Campaign titles imported as if they're IDs.

After

Only numeric values are searched by ID.

Technical Details

This has to do with how MySQL casts the value, but we should fix this at the import layer, not the API/db layer.
