expression.callee is undefined when evaluating custom decorators

[wassim-ben-amor]

Hello, when using the linter, I have an error exactly here:

stencil-eslint/src/utils.ts

Line 50 in 506dba7

return dec.expression && dec.expression.callee.name;

When debugging the linter run, I have found that dec.expression.callee is undefined. The name of the decorator is situated directly on dec.expression. This issue is happening when using the decorator in this way:

@BindToInstance
  async onApply(
  ... 

instead of

@BindToInstance()
  async onApply(
  ... 

Do you agree to change it to:

function decoratorName(dec) {
  if (!dec.expression) return undefined;
  const { callee, name } = dec.expression;
  return callee ? callee.name : name;
}
