No Provider Crash

[0x4007]

On my Safari there is no wallet provider and it throws an error and hangs at "loading..." this should be caught and handled.

---

Strangely enough it crashes on Safari right at the function execution but technically that's not in scope of the bounty. But still concerning that there's inconsistencies with Safari and Chrome for a simple promise.

[Error] Unhandled Promise Rejection: Error: missing provider (argument="provider", value=undefined, code=INVALID_ARGUMENT, version=providers/5.7.2)

	(anonymous function) (app.ts:8)
