Issue

When a file is not open in a window and is to be edited in the current window, :drop adds an extra jump, which is a duplicate of the current position, at the tail of the jumplist.
This makes it necessary to press <CTRL-O> twice to go back to the previous cursor position.

Steps to reproduce using nvim -u NORC

Given the following two files:

#file1
file1 contents

#file2
file2 contents

The following does not work as expected:

nvim -u NORC file1
:drop file2
<CTRL-O>

Actual behaviour

nvim -u NORC file1
:clearjumps
:drop file2
:jumps

 jump line  col file/text
   2     1    0 file1
   1     1    0 file2 contents
>

Expected behaviour

nvim -u NORC file1
:clearjumps
:drop file2
:jumps

 jump line  col file/text
   1     1    0 file1
>
