EISDIR error when paths.sources directory name contains .

[AntonGulak]

Solidity Coverage crashes with the error "Error in plugin solidity-coverage: Error: EISDIR: illegal operation on a directory, read"

For example, if the contracts are in the ./Solidity-4.21 directory (crashes because of a dot in the folder name)

paths: {
sources: ./Solidity-4.21,
tests: "./test",
cache: "./cache",
artifacts: "./artifacts",
},

Thanks again @AntonGulak! This should be fixed by #880.
