MDEV-36633 MDEV-35452 spider/bugfix.mdev_33434 reports wrong error in view protocol

Browse Source 
With view protocol collation_connection is reset in mysql_make_view in
the "SELECT * FROM mysqltest_tmp_v" query. In the case of
spider/bugfix.mdev_33434, it is reset to latin1_swedish_ci, with the
latin1 charset.

This results in no conversion needed since it is the same as
character_set_client and the corresponding argument in the udf remains
unchanged, with "dummy" srv value. Thus the reported error is

1477: 'The foreign server name you are trying to reference does not exist. Data source error:  dummy'

Without view protocol, the character_set_connection ucs2 setting in
the test survives, and the conversion results in empty connection
parameters, and the reported error is 1429
ER_CONNECT_TO_FOREIGN_DATA_SOURCE

This failure is irrelevant to the test, or to spider at all. Therefore
we disable view protocol for the statement.
