I'm opening this issue because:

• I'll report a minor issue

Description

Steps to Reproduce

Please provide detailed steps for reproducing the issue.

1. Open any site (https://github.com)
2. Press n or N
3. You will see the following:

I think we should ignore n/N until search is started.

System configuration

• Operating system: Windows 10
• Firefox version: 60.0
• Vim-Vixen version: 0.12

Vim says when n pressed with no previous searchs:

E35: No previous regular expression

Vim Vixen should say such messages (e.g. "No previous search"...)

@ueokande, looks like my vim saves last searched pattern somewhere. Even when I close the vim and reopen it again I cannot see message "No previous regular expression"

But i'm okay with something like "No previous search" instead of "Pattern not found: null". Looks more user-friendly

current message expose the internal implementation. I'll fix it in the next version.
