grid_scan command doesn't work anymore

[bisogni]

We are running a usual "grid_scan" command that we use at all restart of the beamline and get an error at each time we use it. This is preventing to go through the beamline alignment procedure.

@bisogni This issue has been fixed in bluesky's master branch, but that fix didn't make it in time for the most recent software roll out. I imagine this problem will affect many beamlines. Thanks for being the first to report it --- I expect you have saved others some trouble!

We'll probably have to do a minor update soon to fix this properly, but I have fixed it manually on xf02id1-ws2 so that you can be un-blocked. All you'll need to do is exit IPython and start bsui again.

[ambarb]

Thanks. We changed hinted to normal and it worked, but after the scan stops we will restart and test.

[ambarb]

It works. Plot is correct. Thanks

[danielballan]

Excellent! Thanks for the confirmation and for the very useful initial report.
