spacy_install() forces update to pip 10, incompatible with spacyr

[prokopyev]

Just trying to get spacyr running for the first time.

spacy_install() leads to

The following NEW packages will be INSTALLED:
    ca-certificates: 2018.03.07-0

    python:          3.6.5-hc167b69_1 

Trying to initialize spacy after this, the error code is as follows:

> spacy_initialize()
Python space is already attached.  If you want to switch to a different Python, please restart R.
Error in py_run_file_impl(file, local, convert) : 
  AttributeError: module 'pip' has no attribute 'get_installed_distributions'

The core problem is described in this pip issue: https://github.com/pypa/pip/issues/5154
