This reverts commit 7f5adf73a0.
This seems to miss the whole point of the idExists flag, as it makes the
lifetime of that being true the same as the lifetime of the Context resource.
The previously current context tag is always given in a MakeContextCurrent
request, even if that context tag is no longer valid (for example, the context
has been deleted), so this leads to BadContextTag errors.
See fd.o bug #30089 for the makecurrenttest.c testcase, and some discussion of
previous manifestations of this bug.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
