Previously _uamlite.sh.tpl would fail to render if any user data
had an empty user_sshkeys array. This is because the template would
check to see if the key existed, but not actually make sure that the
array contained within that key had any elements. "first" would be
called against the empty array, which would return nil, and then
the outer eq function call would fail (as it can't be used to
compare nil values).
This patch set adds a default statement after the "first" function,
so that if the array is empty and first returns nil, a default of
"Unmanaged" will be returned, which will end up making the eq
statement evaluate to false, and the code inside the if statement to
not be run.
