Issue Summary

I am upgrading from 0.7.5 I have successfuly got to 8.0 but when try to start ghost after making the required changes per the upgrade documentation I get this error Unhandled rejection TypeError: Cannot read property 'context' of undefined I have had a look at the code and found it was occuring on line 89 of the core/server/index.js tried removing context just to see what would happen and it still happens.

Steps to Reproduce

1. Have a install of ghost 7.5 and upgrade to 0.8.0
2. Copy the new core folder over for 0.9.0 along with the index.js and json files listed in upgrade guide
3. Remove the node_modules folder
4. Run npm install --production
5. Run npm start --production
6. Watch migration fail

Looking further into this I tried to remove all trace of node modules by removing the node_modules folder and running npm cache clean then reinstalling the node modules again and the same error happens. I have also tried commenting out line 89 and the same error occurs, could it be a bluebird issue not a ghost issue ?

[LaraEzarik]

Looking at the errors again I took a look at bluebird and tried changing the version from 3.4.1 to 3.4.5 and the same error occurs, now looking at the database as the possible issue here.

The issue is now resolved it was down to a faulty database missing data in the visibility for tags and users, I added them all manually and it now works.
