Changed some bad comments referencing the Articles module in other modules.
Typo fixed in xxx.client.modules.js files ("Application" => "Applicaion")
Full stop character removed at the end of line comments
Adds an additional check for the existence of a populated user
reference, when determining if the current user has immediate access to
the requested article.
Without this fix, the server will throw an error if the requested
article doesn't have a populated user field.
Modified the article & articles list view's to check if the article has
a populated user. If not, then it will display "Deleted User" in place
of the missing user reference.
Added a server-side test that ensures we can get a single article if
the article.user field is referencing a deleted user.
Fixes#1082
The bug was not exposed by the original test, since it was mixing two (related) aspects:
* An invalid Id (a badly formed mongodb identifier)
* An non-existent Id (an identifier with no corresponding document in the database)
Modifications:
- Fixed the message property in the article controller (the error message follows the wording of the error message in "users.password.server.controller.js", in case of username not found)
- Added a new test to check modifications and avoid regressions
