Write takes argument from the last Write keyword executed

Nobody has claimed this yet.

This is a similar, if not identical issue to [issue387](https://github.com/robotframework/SSHLibrary/issues/387).

I have the following keyword sequence:

```
Write source /home/file\n
Read Until Prompt strip_prompt=True
Write rm -rf /path/to/some/other/dir
Read Until Prompt strip_prompt=True
```

The TRACE return of the second Write keyword is:
`TRACE Return: ' source /home/file\r\n'`
and the TRACE return of the second Read Until Prompt keyword is:
`TRACE Return: 'rm -rf /path/to/some/other/dir\r\n'`

So it seems that the argument of the first Write keyword was queued on the remote system, and the second Write keyword argument was returned as the stdout of itself (rm -rf /path/to/some/other/dir had a stdout of rm -rf /path/to/some/other/dir)

Any help is appreciated

Start by reproducing the reported sequence of Write and Read Until Prompt keywords and inspect their TRACE returns, comparing the behavior with issue387. Done means consecutive Write calls no longer return an earlier argument and Read Until Prompt returns the expected remote output.
