Crashes when Bearer token is blank in BearerStrategy

[jthorel]

Version: 4.2.1

If the Authorization header is formed as: Authorization: Bearer
(that is, just a blankspace after "Bearer") the token will be an empty string and will crash the server in the authenticate method.

The issue is here:

passport-azure-ad/lib/bearerstrategy.js

Line 529 in 48d44bb

self.failWithLog('In Strategy.prototype.authenticate: missing access_token in the header');

It should return:

return self.failWithLog('In Strategy.prototype.authenticate: missing access_token in the header');
