View creation code fixed to expect empty TABLE_LIST::table pointer (BUG#15096).

mysql-test/r/view.result:
  BUG#15096 test suite.
mysql-test/t/view.test:
  BUG#15096 test suite.
sql/sql_view.cc:
  View placed in a function never get TABLE during view creation,
  because we have never executed that function in this process.
  So we should expect empty TABLE_LIST::table pointer.
