Fix compile new bpl

[isc-pbarton]

Description

Resolves #984
Fixes two unrelated bugs causing compilation failures:

• logic to auto add bpl/br to source control assumed that if compiled class dictionary exists it is runnable, which is apparently not true
• RefreshUncommitted calls a git status and output is incorrectly parsed, leading it to try to look up internal name for an empty string.

Testing

A little hard to unit test because it only occurs in certain edge cases in the compile chain. Manual testing:
docker compose up -d --build
do ##class(SourceControl.Git.API).Configure()
enter in prompts to initialize git repository, accepting all other defaults.
http://localhost:52774/csp/sys/UtilHome.csp
Create a new business process (simplest compilable one: just add one Trace block, set value to 1, then hook it up to the input and output).
Save the business process
Compile. Prior to this change, it failed to compile. Now, it successfully compiles.
Open Git Web UI and confirm the new business process was automatically exported to the Git workspace.

Checklist
