>>> m = np.ma.array(["hello"])
>>> np.ma.take(m, 0)
  File "\numpy\ma\core.py", line 5670, in take
    out = _data.take(indices, axis=axis, mode=mode)[...].view(cls)
TypeError: string indices must be integers

Since np.string_[...] is not supported

Introduced by #7586

BUG: Fix np.ma.take on un-indexable scalars
e93926b 
np.string_ scalars cannot be indexed with [...], and np.object_ scalars do
not even exist.

The only way to make this work is to not allow a scalar to be produced in the first place - which can be achieved by adding an extra dimension to the indices, and removing it while allowing 0d arrays

Fixes numpy#9206
