useless-import-alias is too strict

[webartifex]

For some common libraries the canonical way to import now causes a pylint warning

Steps to reproduce

1. pip install rpy2
2. import rpy2.robjects as robjects
3. or, import rpy2.rinterface as rinterface

Current behavior

pylint issues the warning "C0414: Import alias does not rename original package (useless-import-alias)"

Expected behavior

This should not be a warning/error

pylint --version output

pylint 2.1.1
astroid 2.0.4
Python 3.6.5 (default, Apr 1 2018, 05:46:30)
[GCC 7.3.0]
