Daniel Hahler d3d9a91ae6 init: improve handling of import errors (#840) ...

* jedi_vim.jedi_import_error: add location

This is useful for debugging.  It contains e.g. the path to parso, if
importing failed from there.

Example:

> Error: jedi-vim failed to initialize Python: jedi#setup_python_imports: could not import jedi: cannot import name 'PythonTokenTypes' (in /…/jedi-vim/pythonx/jedi/jedi/api/completion.py:1). (in function jedi#init_python[3]..<SNR>44_init_python[27]..jedi#setup_python_imports, line 37)

* init: handle jedi_vim.jedi_import_error in Vim plugin

Using `set shortmess+=F` would suppress the `:echom` used in
`jedi_vim.no_jedi_warning` [1].

This patch makes `jedi#setup_python_imports` handle the error instead.
