[clang-tidy] Fix RenamerClangTidy handling qualified TypeLocs

Summary:
Previously if a type was accessed with a qualifier, RenamerClangTidy wouldn't rename the TypeLoc, this patch addresses this shortfall by trying to find the Unqualified TypeLoc first. Also fixed a broken test case that was dependent on this broken behaviour.

Example:
```
struct a{};

void foo(const a&);
void foo(a&);
void foo(a);
void foo(a&&);
void foo(const a);
```
exec `-checks=readability-identifier-naming --config="{CheckOptions: [{key: readability-identifier-naming.StructCase, value: CamelCase}]}" -fix`
Current Behaviour:
```
struct A{};

void foo(const a&);
void foo(A&);
void foo(A);
void foo(A&&);
void foo(const a);
```
Proposed new behaviour:
```
struct A{};

void foo(const A&);
void foo(A&);
void foo(A);
void foo(A&&);
void foo(const A);
```
