Error when first VCS root is not GIT

[DVGeoffrey]

Was expecting a webhook request on build finish and never got one. Looked at the server logs and found this:

Seems to be an issue with this line:
https://github.com/cloudnative/teamcity-webhooks/blob/master/src/main/java/io/cloudnative/teamcity/WebhooksListener.java#L67

Can't be sure but it looks like theres an assumption that the first "VCS Root" is GIT. Most of my projects use SVN so I got this error. When I added a dummy GIT repository and made it the first checkout, I started getting webhook requests again.

@evgeny-goldin Would you mind taking a look at this please?

Thanks.

Thanks for diagnosis, Geoffrey. I'll change the code to skip non-Git VCS roots.

Has this gone into the released code yet? I'm having the same issue since I'm only having a Subversion repo. Is there a way to patch this?
