Describe the issue you encountered:
After removing the brave user data dir I receive the following messages on startup

[29254:0830/124921:ERROR:connection.cc(1912)] Web sqlite error 14, errno -2: unable to open database file, sql: -- sqlite3_open()
[29254:0830/124921:ERROR:web_database_backend.cc(56)] Cannot initialize the web database: 1
[29254:0830/124921:WARNING:brave_browser_context.cc(73)] initializing autocomplete database failed

If you attempt to save any autofill data on the first run it will be blank when you run brave again

Expected behavior:
autocomplete database should load on first run

• Platform (Win7, 8, 10? macOS? Linux distro?):
  macOS
• Brave Version:
  0.11.6dev
• Steps to reproduce:
  1. Delete or move your brave user data dir
  2. Run Brave in dev mode (to get console output)

additional testing steps:

1. delete or remove your brave user data dir
2. run brave
3. add an autofill address
4. quit brave
5. re-open brave
   The autofill address should exist and have the correct values

I think this issue still exists on Windows 7 64 bit.

1. Move your brave folder
2. Open autofill settings from about:preferences#security
3. Click on Add Addresses
4. Input temp in the field Name
5. Quit the browser
6. Start the browser

The name field becomes blank.

Reopening for now.
