ValueError when retrieving timeseries

When I try to request timeseries via ek.get_timeseries a ValueError is thrown (only for specific stocks/parameters).

Example snippet with traceback:

>>> ek.get_timeseries(rics=['GHG.BH'], fields=['OPEN', 'CLOSE'], count=5)
Traceback (most recent call last):
  File "C:\Program Files (x86)\Python37-32\lib\site-packages\pandas\core\internals\managers.py", line 1677, in create_block_manager_from_blocks
    make_block(values=blocks[0], placement=slice(0, len(axes[0])))
  File "C:\Program Files (x86)\Python37-32\lib\site-packages\pandas\core\internals\blocks.py", line 3265, in make_block
    return klass(values, ndim=ndim, placement=placement)

    "{mgr}".format(val=len(self.values), mgr=len(self.mgr_locs))
ValueError: Wrong number of items passed 1, placement implies 2

During handling of the above exception, another exception occurred:

ValueError: Empty data passed with indices specified.

It seems like the reason for the error is that there are no up-to-date quotes (latest GHG.BH quote is from 2019-11-04) and the number of returned rows is limited via the count param.

The ValueError is also thrown when data for multiple rics is requested, so one 'bad' ric that has no current quotes crashes the whole batch-query. I am pretty sure that this behaviour is not intended and that it should be fixed.

I've tested it on eikon version 1.0.1 and pre-release 1.1.2b0. If necessary I can provide additional examples (e.g. other rics that cause the same behaviour).
