Looking at the code for the 1.4.5 release of git-client-plugin it looks like the failing line 894 is

for (RemoteAgentFactory factory : Jenkins.getInstance().getExtensionList(RemoteAgentFactory.class)) {

That would suggest that it is not finding any RemoteAgentFactory instances in getExtensionList().

This is a remoting issue. Code is ran on slave and can't access Jenkins.instance.
Have to improve the test suite to run with remoting enabled (see remote branch on github)

stop using ssh-agent plugin that can't be used from remote

it is not possible to obtain the Jenkins instance from a node, so we go
