Description

The following changeset 76d074825f27294cf1bb6081628a8d988dc1cc18 broke the ability for the ParaView MDEventNeXus file reader plugins to actually read files. The error seen is 

AnalysisDataService-[Warning]  remove 'MD_EVENT_WS_ID' cannot be found
LoadMD-[Notice] LoadMD started
LoadMD-[Notice] LoadMD successful, Duration 0.00 seconds
AnalysisDataService-[Warning]  remove 'MD_EVENT_WS_ID' cannot be found
LoadMD-[Notice] LoadMD started
LoadMD-[Error] Error in execution of algorithm LoadMD
LoadMD-[Error] NXopen(/home/2zr/git/mantid/Test/AutoTestData/SEQ_MDEW.nxs, 2) failed

This error happens no matter what type of MDNeXus file I try to open in ParaView or VatesSimpleGui.

I'm including Owen on the ticket in case this has to do with how the reader handles the FileBackEnd flag.

Refs #5001: perhaps the nxs file was not getting closed properly

before being reopened in Read-Write mode. It seems that loading the meta data with 'FileBackEnd' set works well.

I'm not 100% sure why it wasn't working (because the temporary workspace for loading metadata should close the file) but this seems to fix the error.
