Don't crash when contribution page is selected as a column

[demeritcowboy]

1. Pick Contribution Page as one of the columns.
2. Type Error crash if there are any contributions that come from a contribution page.

A couple things:

• This function alters the display value for a column in the report. Returning array makes no sense. Should be string, possibly null but '' makes more sense than null.
• The commit that caused this I assume was some phpstorm-suggested mass-replace based on docblocks.
  • The docblock in core is wrong. It's another of those functions that returns an array or string depending on the param. I'll make a separate PR in core for that.
  • That function is deprecated, but title is not a valid field for buildOptions for contribution pages (returns FALSE), so it's not really deprecated and I can't replace this call here with a call to buildOptions.

Thanks @demeritcowboy @seamuslee001 @KarinG - I'm happy to tag a release if you wish - civi compatibility of the release is set to 5.55 & that can probably stay the same

Thanks!
I don't know about a release. It's an easy patch but I'll let others comment.

A release would be great 👍
