Fix labels and dependencies not saved in daemon mode (fixes #101)

The daemon's handleCreate function was ignoring createArgs.Labels and
createArgs.Dependencies, causing labels and deps specified during issue
creation to be lost when using daemon mode.

Added label and dependency processing after issue creation to match
the direct mode behavior in cmd/bd/main.go.

Fixes: #101
