Fix when component is undefined

[codetheweb]

Changes

A bug seems to have been recently introduced in v12:

This happens because

lock/src/ui/box.js

Line 59 in b708c30

this.modals[containerId].component.hide();

assumes that if this.modals[containerId] is defined, this.modals[containerId].component is also defined. But this isn't always the case:

lock/src/ui/box.js

Line 42 in b708c30

this.modals[containerId] = { root };
