vfb.terms breaking changes in interface

[jefferis]

According to https://virtualflybrain.org/docs/tutorials/apis/vfbconnect_neuron_display/ this should work:

> neurons = vfb.terms('5th s-LN')
Notice: No exact match found, but potential matches starting with '5th s-LN': 
'5th s-LNv (FlyEM-HB:511051477)': 'VFB_jrchk8e0', 
'5th s-LNv': 'VFB_jrchk8e0'

But instead I see:

>>> from vfb_connect import vfb
>>> neurons = vfb.terms('5th s-LN')
Traceback (most recent call last):

So I think string input no longer works?

Furthermore if the query fails:

>>> neurons = vfb.terms(['5t sLNv'])
No direct match found for 5t sLNv
Error: Unrecognized value: 5t sLNv
