Set sequence_range to 1 while initialising nodes for "make check" so that

deterministic output is obtained.

This avoids explicit setting of the GUC in every test case that uses serials or
sequences. For those running "make installcheck" they must set it up correctly
in their postgresql.conf files.

We could revert some of the changes done to the test cases (by adding
sequence_range = 1), but this patch does not do that
