Bug: configure macro SVN_FIND_APR makes improper use of `test'

In the file ac-helpers/apr.m4, there is one case of `test -z' where
the variable tested is not quoted, to be specific the test on $APRVARS
in the macro SVN_FIND_APR. This is of course bogus since if the
variable really _is_ zero length, `test -z $APRVARS' will cause test
to be called with just one argument (-z), which is not what you want.
The other use of `test -z' in this file is correctly quoted so I
expect this was just a minor slipup.
