[mandres-digix]

The role was not included in the check for valid users. This diff should fix that.

Test Plan

Setup

The test account for PRL is account. Check that it's recognized by info-server by going to localhost:3001/address/$ADDRESS. If the result is notFound, you need to add the address as a PRL account to the info-server and dao-server.

For info-server, you can add it via mongodb:

$ mongo
> use digixdao
> db.addresses.insertOne({ address: "$ADDRESS", isPrl: true })

For the dao-server, you can add it via rails console:

$ rails c
> User.create(address: "$ADDRESS", uid: SecureRandom.rand(1000000..1999999))

Test

• Use account1 in development environment and try to load the wallet.
• The user should be able to sign the message and use the site successfully.
