Added not null check when collecting RefsSoyData

When using gitiles in gerrit through the gitiles plugin sometimes it
happens that access rights inhibit the view of a Ref for a specific
user, giving a null Reference which is producing ugly NPE [1].
In such case this change is simply dropping the Ref and not returning it
in the list to the caller.

[1] here is last part of the returned exception:
java.lang.NullPointerException
at com.google.gitiles.RefServlet.getRefsSoyData(RefServlet.java:171)
at com.google.gitiles.RefServlet.getBranchesSoyData(RefServlet.java:106)
