Comment 1 for bug 1760599

I created a branch to fix this, called user/sandbergja/lp1760599_disable_merge_records_unless_multiple_records_selected

Here's a link: http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/sandbergja/lp1760599_disable_merge_records_unless_multiple_records_selected

Here are testing instructions from the commit message:

1) Create a bucket.
2) Select one record from your bucket. Right-click on your record or click on the Actions drop-down.
3) Note that "Merge Selected Records" is clickable.
4) Apply this commit.
5) Repeat steps 2-3. Note that "Merge Selected Records" is no longer
clickable, unless you select two or more records.
