Cypress wait workarounds needed

[scottohara]

In authentication/edit.spec.ts, a cy.wait(300); is needed to ensure the bootstrap modal is ready before typing; otherwise the first character is sometimes missed.

In og-components/og-table-navigable.ts, a cy.wait(200); is needed before key navigations so that the click to focus the first rows completes; otherwise we get a Transition Rejected error due to the click state transition being superceded by a key state transition.
