Fix token auth (instead of setting headers)

[ohartl]

Fixes #19, #27 and #30. Also makes #15 obsolete.

I noticed that token auth wasn't working and having my password in plain text isn't an option.

Seems like Object.assign throws the error Cannot convert undefined or null to object because options.headers wasn't defined before. But i decided, instead of setting the headers to empty object above (like #15 does), using the options.auth to keep it consistent. The code for token auth previously must have been missed that part when updating to options.auth.

The failure grabbed from VSCode Extension Host Logs was

@janjoerke Ping back, this is important to make the plugin work for Jenkins API Token auth again.

@ohartl @janjoerke Hi, I'm having this issue. Maybe you have news on resolving this? thanks, regards

[jhd235]

@ohartl any news, please?

I'd like to see this merged as well. It's not intuitive to paste the token code in the password field when there is a designated token setting field.

Is there a way to get the plugin with the fix? Anyway to compile locally and install it with the fix?

Would love to see this merged - I've manually made this change on my local install and it fixes this problem
