Posterverse: don't overwrite a link to a tab that arrives with the manifest

Browse source 
The first-paint write is skipped when the address names a tab the shell
doesn't know yet (a row that only resolves once the manifest is in). Writing
tab 0 there would replace the link before applyManifest could honour it;
applyManifest's own first-paint replace writes the honoured tab.
