to look at the new patch set (#14).

Change subject: ASTERIXDB-1487: fix the wrong plan when we prune the selective 
branch.
......................................................................

ASTERIXDB-1487: fix the wrong plan when we prune the selective branch.

1. Add the test case of ASTERIX-1487 with single join branch required.
2. Disable the join branch pruning in case of unnestmap following 
datasourcescan.
   - We need to prune the join branch when it is NOT required by the upstream 
operators and its generated join key is derived from the same DATASOURCE of the 
other branch.
   - We SHOULD NOT prune the join branch if there exists a selective operator 
(UNNESTMAP, LOUNNESTMAP, LIMIT, SELECT) located between the join operator and 
DATASOURCESCAN.
