Fix DeprecationWarning on autocompletion with jedi 0.17.0

[gorogoroumaru]

with jedi 0.17.0

In [1]: import warnings
In [2]: warnings.filters.remove(('ignore', None, DeprecationWarning, None, 0))
In [3]: a=0
In [4]: a.<TAB>

throws a deprecation warning below

DeprecationWarning: Providing the column is now done in the functions themselves like Script(...).complete(line, column)

So, I fixed it.

Thanks, I had to rebase on master to get the test to pass (they were failing for an unrelated reason).
