Vitaliy Zakaznikov 13978c03f3 * Fixing a bug in StorageLiveView.cpp in the getHeader() method
when header block would not match blocks in the stream
  when Const column is present.
* Updating 00963_temporary_live_view_watch_live_timeout.py
  and removed timeout=5 after WATCH query is aborted with Ctrl-C
  so that the default timeout of 20sec is used
* Small style fixes in tests
