Fix list view heights for delete lists

[seadowg]

Closes #5594

What has been done to verify that this works as intended?

Verified manually.

Why is this the best possible solution? Were any other approaches considered?

No other option here - the height for the list views was incorrectly set to fill the whole screen (rather than the available space).

How does this change affect users? Describe intentional changes to behavior and behavior that could have accidentally been affected by code changes. In other words, what are the regression risks?

As I pointed out in the issue, this ended up being pretty hard to reproduce as you need the exact right number of forms so that the bottom one is cut off, but that there are not enough forms to actually scroll. I think just checking scrolling on the "Delete form" page (for Saved and Blank forms) is enough here.

Before submitting this PR, please make sure you have:

• run ./gradlew checkAll and confirmed all checks still pass OR confirm CircleCI build passes and run ./gradlew connectedDebugAndroidTest locally.
• verified that any code or assets from external sources are properly credited in comments and/or in the about file.
• verified that any new UI elements use theme colors. UI Components Style guidelines
