remove dep on globalthis

[jimmywarting]

seriously, you do not need globalThis...

clientjs/src/client.base.js

Lines 580 to 586 in 08cb26b

	isLocalStorage: function() {
	try {
	return !!globalThis.localStorage;
	} catch (e) {
	return true; // SecurityError when referencing it means it exists
	}
	},

just use typeof LocalStorage !== 'undefined' instead... don't even need a try catch for that...
