This patch indroduces a check before unsetting an array element.
Without this, gitk may complain with
can't unset "prevlines(...)": no such element in array
when scrolling happens.

There's an error that seems to occur in gitk only on
mutt's imported repo, but I don't know why. This is
hopefully the right fix.
An example of this error:
can't unset "prevlines(a3b4383d69e0754346578c85ba8ff7c05bd88705)": no such element in array
can't unset "prevlines(a3b4383d69e0754346578c85ba8ff7c05bd88705)": no such element in array
while executing
"unset prevlines($lid)"
