Tooltip: add type/empty check for its value

[hakiiver2]

Shouldn't we check if the type of this "options.value.value" is a "String"?

primevue/src/components/tooltip/Tooltip.js

Line 341 in d77c9a4

if (options.value.value === undefined || options.value.value === null || options.value.value.trim() === '') return;
