Creating a buffer with :new overwrites existing scratch buffer if read from stdin

[yonatan8070]

Summary

When piping data into helix via stdin (echo "..." | hx) and the creating a new buffer via :new (without writing the first buffer), the data from the first buffer will be deleted.

I noticed that if I modify the stdin buffer before using :new it does not get deleted, I'm assuming this is because before it's modified it is wrongly considered an empty buffer, since I also noticed that :q works without prompting to save the buffer before leaving.

Reproduction Steps

I tried this:

1. echo "Hello, world!" | hx
2. :new

I expected this to happen:
A new scratch buffer is created alongside the data from stdin.

Instead, this happened:
The buffer created from stdin was deleted and a new scratch buffer replaced it.

Helix log

There was nothing written to the log during my testing.
