Log scale validation too strict againts null values

[tflanitzer]

When using a line with a log scale on data that has null or undefined values, an exception is thrown ("a log scale domain must be strictly-positive or strictly-negative"). However, when the check is removed (packages/scales/src/logScale.js:19), the line displays fine with gaps, as expected. I have created PR #1099 with a possible fix.

To Reproduce
To reproduce the validation error, just use a null value in a data set with a log scale. See this codesandbox.

Expected behavior
Like with linear scales, data points without value (null or undefined) should just not be displayed and the line should be separated.

Screenshots
Here is a screenshot proving that it works with the validation disabled.
