Fix some deprecation warnings (#872)

Fixed
* conftest.py:30: DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses
* mslib/msui/mscolab_project.py:486: DeprecationWarning: an integer is required (got type float).  Implicit conversion to integers using __int__ is deprecated, and may be removed in a future version of Python.
* mslib/msui/mscolab_project.py:647: DeprecationWarning: an integer is required (got type float).  Implicit conversion to integers using __int__ is deprecated, and may be removed in a future version of Python.
* mslib/msui/topview.py:354: DeprecationWarning: In future, it will be an error for 'np.bool_' scalars to be interpreted as an index
