With the `if` conditional around this statement, `options` will always
be evaluated as truthy. That means that the nullish coalescing operator
will always evaluate to the left side, make it unnecessary.

The FS docs wrongfully indicated support for passing object with an own
`toString` function property to `FileHandle.prototype.appendFile`,
`FileHandle.prototype.writeFile`, `FileHandle.prototype.write`,
`fsPromises.writeFile`, and `fs.writeSync`. This commit fixes that, and
adds some test to ensure the actual behavior is aligned with the docs.
It also fixes a bug that makes the process crash if a non-buffer object
was passed to `FileHandle.prototype.write`.

When the file read position is moved passing zero is
not respected and `null` is used instead. PR fixes the
issues by using nullish coalescing which will return

This increases performance by reading more data (and, most likely,
all data) at once without incurring memory overhead in most situations.
