This reverts commit 7f5adf73a0f9a951a6df201532b4031d38054369. 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The previously current context tag is always given in a MakeContextCurrent request, even if that context tag is no longer valid (for example, the context has been deleted), so this leads to BadContextTag errors.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.
