The problem was that empty progress messages were being converted to
`None` which `AlgorithmObserver` did not have the proper overloaded
methods to convert to an empty string. The fix is to convert them to a
string before calling the binding. For extra measure, the progress
percentage is converted to a float as well.

When renaming workspaces in a Python script, two threads were accessing
m_selectedNames and m_renameMap; one of them calling the clear() method
and the other keys(). To prevent the race condition there, the methods
in question now acquire a lock before any read/write operation.
