plasma network manager doesn't prompt for password on vpnc connections

[Daniel Nicoletti]

[Impact]

My co worker has a vpnc connection that requires authentication
using a token app, it seems that even if it just requires a
regular password the issue would be the same.

We talked to the maintainer and helped doing
tests, in the end this commit fixed the issue:
https://projects.kde.org/projects/extragear/base/networkmanagement/repository/revisions/64988f79dc199bbd4e96db0ea34f8c5bb6450747

We feel it's important to backport the fix
so other users of vpnc with password connections
can have it working too.

[Test Case]

 * have a vpnc that requires a password, and
set it up as it should ask the password every
time. Or have it work with random tokens.

[Regression Potential]

* We have used all other features without
noticing any regression.
