What problem does this PR solve?

Since Go 1.15, expression "string(int)" to make type casting from int to string are not allowed.
Check more info at golang/go#3939.

Run make test at Go 1.15 env would lead to below error:

./lexer_test.go:204:12: conversion from untyped int to string yields a string of one rune, not a string of digits (did you mean fmt.Sprint(x)?)

What is changed and how it works?

Replace such casting expressions to other legally expressions.

Make test will fail due to Go1.15 starts to not allow "string(int)" expression.
Fix affected sources by replace such expression to legal expressions.

More info about ban string(int), see: golang/go#3939
