Upload OSM Tool reports +1 features uploaded than actual

[eggwhites]

When the Upload OSM Data tool is run, the log messages will report how many features are uploaded to the OSM endpoint. The message will report one more than the actual result; e.g., if you digitize ten points, the message will report eleven features uploaded. If for some reason no features are uploaded, the tool will report that one was.

Desired behavior: tool should report number of features uploaded accurately.
