Remove follow-imports argument which may conflict with projects

mypy prioritises values from configuration on its command line
over that provided in configuration files. This means that the
value previously provided here could override the settings for a
project, cause spurious errors and/or hiding true errors.

Removing this default value allows users freedom to configure
their projects however they like, without the extension injecting
unexpected additional configuration within the IDE context.

Fixes microsoft#89
