Make 01565_query_loop_after_client_error slightly more robust

Browse Source 
CI founds one failure of this test [1], which is quite interesting, the
test itself should not takes too long:

But for the last INSERT the client itself works **very slow**, which
seems was the reason why "\r" had been sent too early and was never
interpreted:

    send: sending "INSERT INTO t01565(c0, c1) VALUES ('1', 1) ;\n" to { exp4 }

    expect: does " " (spawn_id exp4) match glob pattern "INSERT"? no
    I
    expect: does " \u001b[21GI\u001b[0m\u001b[J\u001b[22G" (spawn_id exp4) match glob pattern "INSERT"? no
    
    expect: does " \u001b[21GI\u001b[0m\u001b[J\u001b[22G\u001b[21G" (spawn_id exp4) match glob pattern "INSERT"? no

    expect: set expect_out(0,string) "INSERT"
    expect: set expect_out(spawn_id) "exp4"
    expect: set expect_out(buffer) " \u001b[21GI\u001b[0m\u001b[J\u001b[22G\u001b[21GINSERT"
    send: sending "\r" to { exp4 }

    expect: does " INTO t\u001b[0m" (spawn_id exp4) match glob pattern "Ok."? no
    
    expect: does " INTO t\u001b[0m\u001b[J" (spawn_id exp4) match glob pattern "Ok."? no
    
    expect: does " INTO t\u001b[0m\u001b[J\u001b[34G" (spawn_id exp4) match glob pattern "Ok."? no

    INSERT INTO t01565(c0, c1) VALUES ('1', 1) ;

    expect: timed out

Here you can see that it matched "INSERT" and then expect receive data
from the client almost byte by byte.

So I hope that expecting the last part of the query should fix the
problem.
