Incorrectly displays "unprotected key" warning when user loads private key then switch to pasting ASCII armored key in My Keys -> Add key

[martgil]

In add_key.htm of My Keys -> Add, the warning message This key is unprotected. Create a pass phrase or use a random one is displayed when a user tries to import the private key file then close the file dialog and proceed to pasting the ASCII armored private key. This is a minor issue hence they will be confused that their key might've been unprotected by passphrase when in fact its a FlowCrypt user bug which incorrectly detects the flow of the previous process after user closes the file dialog.

Screenshot:

Steps to reproduce:

User should already have FlowCrypt setup and valid keys imported to it.

1. Go to FlowCrypt Settings -> My keys.
2. Click on Add Key.
3. Click on Load from a file and then, close the file dialog. (do not choose your private key, for instance, user change of mind).
4. Click on Paste armored key directly.
5. [Important step] Paste a valid and password-protected ASCII armored private key.
6. Observe you'll be seeing the following warning that the private you've pasted is unprotected.

Expected behavior:
The message This key is unprotected. Create a pass phrase or use a random one should not be displayed when user doesn't go for generating a new key.

Current behavior:
The aforementioned message is displayed even when the user selected Paste armored key directly from which they would be providing the existing key private key.

I rechecked this issue, and unfortunately, I can no longer replicate it, whereas before, it could be replicated as simply as the steps above.
