Update basic object with current location report output type

[mikejritter]

What does this do?

• Updates mime type for Basic Object with Computed Location

Why are we doing this? (with JIRA link)
Jira: https://collectionspace.atlassian.net/browse/DRYD-1451

This is updates so that xlsx output is set by default, as it has a way to both provide tabular data and thumbnails. As the workflow is still being tested, we're only adding this to a single report so that we can understand how it might work with, e.g. mail merge.

How should this be tested? Do these changes have associated tests?

• Rebuild collectionspace
• Create a collectionobject
• Search for collectionobjects
• Select the Basic object with current location report and see xlsx as the default output

Dependencies for merging? Releasing to production?
None

Has the application documentation been updated for these changes?
No

Did someone actually run this code to verify it works?
@mikejritter tested locally

@ray-lee apparently I can't convert this to a draft, but I think we should hold off on merging this because I was supposed to do some additional testing of the report with multiple rows. I'll let you know when it's ready.

I ended up here and was somehow able to convert it to a draft. I can change it back if that's annoying.
