Make Contacts available only when profile exists

[buberdds]

Option 3 from Slack thread:

What we want to do with features like Contacts when user is not using persisted state (profile):

• doesn’t matter we show it always
• hide Contacts tab
• show Contacts tab with a different empty state and without Add Contact button
• store Contacts in persisted store and under another localStorage key. Like theme where it is stored under selectedTheme key and oasis_wallet_persist_v1 (state)
