Plugin should ignore corrupted cache

[ezolenko]

Sometimes cache gets corrupted, and plugin throws JSON exception (when build interrupted in wrong place).

[10:30:58] Error: ./.cache/0e05bd66949fbb4a048b752195b45acaa4973026/code/cache/1ebf05433ba5ed0b148851cac444c0fb84ba87c1: Unexpected end of JSON input

Should catch and fallback instead. Alternatively, use transactions.

Workaround -- cleaning cache and rebuilding.
