[PATCH] report-error: Fix tracebacks

[Richard Purdie <richard.purdie@linuxfoundation.org>]

Currently the code gives tracebacks if there are no recipes to be built in a 
BuildStarted event. Parse the list into a string rather than just taking the
first item. There is nothing special about the first time.
