Nuke Studio hangs when opening a project with already localised files
This happens with files localised using on, on-demand or auto-localization path

CentOS 7

Steps to reproduce

1) Open Nuke Studio and open the project /netshare/support/tickets/slowProject/SlowProject_v004_localisationTesting.hrox
2) In Edit>Preferences...>Performance>Localization set the auto-localise from path to your mount to the netshare drive, and increase the storage limit to 60GB
3) Press OK and wait for the project to localize
4) Once the project has localized, close Nuke Studio.
5) Re-open Nuke Studio and open the project, it will now hang after opening as all the files are being checked, and easiy way to check it to try an resize the UI panels

Expected behaviour
For Nuke Studio to open quickly, knowing all the files are in place

Actual behaviour
After Nuke Studio has opened, the whole UI hangs/freezes for a while until it has checked that all the files are still on the local drive

Disable localisation
