ZORBA_URI_PATH and ZORBA_LIB_PATH ignored in root_static_context.cpp

[William Lee]

In root_static_context::init the lRootURIPath and lRootLibPath lists are populated with built-in values and then used to set the uri/lib path via set_uri_path and set_lib_path. The code then updates lRootURIPath and lRootLibPath using the value of ZORBA_URI_PATH and ZORBA_LIB_PATH... but this has no effect as the values have already been copied via set_uri_path and set_lib_path.

The attached patch pushes the calls to set_uri_path and set_lib_path to after the retrieval of environment variables meaning the environment variables are no longer ignored.
