  1. BUG: fix issue with sparse concatting 

    This was originally brought up in :issue:`18686` and :issue:`18914`.
Basically the problem is when you use get_dummies with sparse=True it
will return a SparseDataFrame with sparse and dense columns. This is in
fact not what we want. What we want is a DataFrame with sparse and dense
columns.

Inside of pandas.core.dtypes.concat is a function that defines the
factory class which needed to be changed.
