Coroutine 'SessionProxy.send_custom_message' Was Never Awaited

[mhanf]

Hello shiny_validate team
I am working on a Shiny Python application that uses sequently the enable() and disable() methods of an InputValidator object.
When I call the disable() method after the enable() one, I consistently encounter the following error:

C:\...\Python\Python311\Lib\site-packages\shiny_validate\validator.py:115: RuntimeWarning: coroutine 'SessionProxy.send_custom_message' was never awaited self.__session.send_custom_message("validation-jcheng5", results)
RuntimeWarning: Enable tracemalloc to get the object allocation traceback

Here is a minimal reproducible example where the described error occurs when the disable button is clicked:

from shiny import Inputs, Outputs, Session, App, ui, reactive
from shiny_validate import InputValidator, check

app_ui = ui.page_fluid(
    ui.input_text("email_address", "Email Address"),
    ui.input_action_button("disable", "Disable"),
)

def server(input: Inputs, output: Outputs, session: Session):
    iv = InputValidator()
    iv.add_rule("email_address", check.required())
    iv.add_rule("email_address", check.email())
    
    iv.enable()
    
    @reactive.effect
    @reactive.event(input.disable)
    def _():
        iv.disable()

app = App(app_ui, server)

Thank you for your assistance in resolving this issue

InputValidator.__session.send_custom_message is an async method. In InputValidator.enable() is code, to await this, but in disable() it's missing. IMO this needs to be changed.
