Fix session restore

Since https://commits.kde.org/kxmlgui/8c9fb02a1d37672b26a03a9dd9e8675743deb269
KXmlGui only triggers a session restore for a window when the
session config contains a "NumberOfWindows" key with a value >= 1.
This commit adds such a key to the Dolphin session config, which
fixes the Dolphin main window restore for KXmlGui versions
containing that commit.

BUG: 502770
