DeleteNamedImport assumes the import declaration is in the form of:
import (
"foo"
)
If an import path is deleted there might be a blank line-sized hole:
import (
)
It'll merge the black hole with the last line to change it to:
import (
)
However the import declaration might be in the following form as well:
import (
"foo")
Whic means after deleting the import path, it changes to:
import (
)
In this case it still tries to merge the line with a non existing line,
causing token.File.MergeLine to panic.
We fix the issue by checking that the import path line is not the last
line to avoid panicing.
Fixes golang/go#20229
