[Emacs] Fix evaluation issue of `mu4e-headers-visible-columns' eval

Browse Source 
This commit fixes a bug introduced in 8c6e622a7c and 69dc8c7d7c where
the mu4e-headers view’s width was set to a dynamic, frame-dependant
value that could not be computed with Emacs launched as a headless
server.

This commit makes this value evaluate when the `mu4e-headers' mode is
activated, and hence it should get the correct width of the current
frame.

On modern-day computers, with wide screens almost everywhere, there is no
reason for the email buffer to open below the email directory and not on its
right, which is why I set the split view to be vertical instead of
horizontal. And to make it more readable, the header window will only occupy
40% of Emacs’ frame, the rest will be given to emails.
horizontal. And to make it more readable, the header window will only occupy
40% of Emacs’ frame, the rest will be given to emails. As you can see, the
width of the mu4e headers is evaluated each time we enter it, so it can react
to the frame being potentially not the same width than earlier.
