tdf#120271 thanks ESC: disable getInvolved for stable 6.1 build

https://lists.freedesktop.org/archives/libreoffice/2019-January/081715.html

with the revelant part being:
AI:   + propose remove it from 6.3 and 6.1-stable (Justin)
AI:   => disable for 6.1 for now

Because it is possible for both getInvolved and donate to pop
up simultaneously (by setting lasttime to 1 for example), it
is best to reset it to 0, so that if re-activated again at some point
(like switching to 6.2) then the 90 day timer will again be
started fresh instead of being triggered immediately.
