[Bug] Slot #input doesn't work properly with a custom input component

[mrOrlando]

Vue2-datepicker version: 3.8.0
Vue version: 2.6.11
Browser: Google Chrome v86.0.4240.198

Steps to reproduce

1. You need to pass the custom input to the input slot and use the variables from the scope (in my example I use b-form-input component from the bootstrap-vue library);
2. Try to enter a date manually;
3. An error will appear in the console.

Expected behavior
If a string comes instead of an event in the handleInputInput method, then pass it to the this.userInput parameter.

Actual behavior
An error occurs because the custom component returns the entered value as a string and not an event. You can find this handler in the source code here.

You can transfrom the input event.

Thanks for the answer, however, it looks like a workaround, if you want I can create a pull request in this update, it is very simple, but it will help to avoid such problems in the future for other developers?
