    Issue #3133: Gimp freezes after selecting a filter preset and...
    
    ... clicking a GimpChain.
    Since commit c0c055b4e9, gimp_chain_button_set_active() emits the
    "toggled" signal. There is no need to emit it separately from
    GimpOperationTool when setting presets with
    gimp_operation_tool_set_config().
    
    In particular, since the "toggled" signal was even sent unconditionnally
    here, our code was ending creating several GBinding for the same 2
    adjustments, which was creating an infinite loop.
    
    (cherry picked from commit 03dc24455ab1616204a9ec8fd20070d4411b0b2c)
