ensure getCallSites return array

[barakd]

I encountered a case using ts log version 3.3.0, typescript version 4.5.2 and node v16.13.1
Where on some errors the getCallSiteHelper will return undefined, and not array.
In such cases the logger will explode the whole server due to the slice operation done in LoggerHelper.ts:50
In this minor adjustment I am aligning the helper to respect it's signature, and make sure we always return an array.

/workspaces/usr/packages/package-a/dist/node_modules/.pnpm/tslog@3.3.0/node_modules/tslog/src/LoggerHelper.ts:50
      error == null ? getCallSites(new Error()).slice(1) : getCallSites(error);
                                               ^
TypeError: Cannot read properties of undefined (reading 'slice')
    at Function.getCallSites (/workspaces/usr/packages/package-a/dist/node_modules/.pnpm/tslog@3.3.0/node_modules/tslog/src/LoggerHelper.ts:50:48)
