Wrong default concept used for sticky notes

RA-1287 introduces "sticky notes". However by default this feature uses the concept CIEL:162169 which is also the concept used to capture the free text of a Visit Note, and this leads to problems.

See: https://talk.openmrs.org/t/bug-in-reference-application-or-sticky-note-module-or-just-the-demo-config/16549

Proposed Solution

1. Add a new concept to the CIEL dictionary specifically for capturing this sticky note. It could have a name like "Comments on Sticky Note", or "Overall comments on short-term media" (or hopefully the CIEL team can come up with something better).
2. Include that concept (via the Reference Application Metadata module)
3. Change the default setting for this feature to use the new concept.
