sqlite URI is not handled right on windows

On Windows machine when I try to connect to some sqlite database file, I am receiving error message that says it was not possible to create (or open) file.
I was inspecting code and found that path which is parsed from given URI starts with '/', and on Windows no valid path starts with '/'.
I send in attachment new version of sqliteconnection.py
with three lines which on windows platform strips unwanted '/' from the left of path.
