Make it compatible with Jira 8 and other SAML apps

[max-allan-surevine]

This should allow you to use the plugins with Jira 8.
It also makes it work if your jira is not in the context path /.
(Although does have issues when it is / . Needs a better Java person than me to figure out!)
And sets username/email/etc sensibly rather than assuming username is email everywhere and not setting real names.

Thank you! I was just starting to write the ComponentManager fix as well.

Unfortunately I'm not sure anyone at LastPass still cares about this since @bcopeland left. :(

I've raised a ticket with LastPass, suggested they get one of their own devs to look at my "alternative context" quick fix. Iirc, it will add "null" to the URL if you host jira in / , and of course /null gets a 404 response.
If they don't merge it, I'll ask them to remove Jira from the list of supported SAML apps. There is actually a Microsoft SAML plugin for Jira that might be worth considering if LastPass give up on it. I haven't had a chance to trial it yet.
