Toast: Crashing when no severity value is provided

[crewcall]

Describe the bug

According to the docs, when adding a toast, theseverity value is optional and it defaults to"info", so when we provide no severity value, the toast should render as an info toast.

But if we use the following code, the rendering of the toast fails.

  toast.add({
    summary: "Info",
    detail: "Message Content",
    life: 3000,
  });

It throws an Unhandled Promise Rejection: TypeError: undefined is not an object (evaluating '$options.iconComponent.name') error.

This code works as expected:

  toast.add({
    severity: "info",
    summary: "Info",
    detail: "Message Content",
    life: 3000,
  });
