homebank: fix clang build

Labels always require a statement behind that. GCC permits declarations
for some reason, but it's against the standard and clang (rightfully)
rejects this.

Adding an empty statement to work around this.

+Notably, only expressions and no declarations are allowed. A common workaround for this
